When the computer is in sleep state, it will cut off the power of other accessories except the memory. The working status data will be stored in the memory. When the computer is restarted again next time, it can directly enter the working state. How to set the sleep mode of Win7 system?
One, short leave with "sleep", let the computer take a nap for a while to use the computer, often there is such a situation: occasionally need to leave for a period of time, long or short, not very fixed, such as at noon or dinner at night in this way. At this time, if you turn off the computer, it seems to be a bit of a big problem, because many programs and web pages have to be reopened when you come back, but if you don't shut down, the computer is wasting electricity, if there is anything to delay, time from one It doesn't matter if the hour becomes two hours, then it's not a waste! It's a bit of a dilemma. What should I do? In fact, you only need to enable the system's sleep function at this time. When you need to wake up after entering the sleep state, you only need to press the power button or shake the USB mouse to quickly resume the working state before leaving and continue to work. The speed can be much faster than restarting after shutdown! And all work before sleep can continue without restarting. At the same time, after entering the sleep state, the computer will only have the memory power-on to save the data of the working state, while the other hardware is all powered off, so the power consumption is very low.
What is "sleep"? When the computer is in sleep state, it will cut off the power of other accessories except memory, and the working status data will be stored in the memory, so that when the computer is reawakened, it can quickly recover before sleep. Working status. If you need to leave the computer for a short time during work, you can use the sleep function to save power on the one hand and resume work quickly on the other. However, you need to be reminded that because the sleep state does not save the desktop state to the hard disk, if the power is cut off during sleep, the unsaved information will be lost, so before the system sleeps, you better save it. The documentation is all & ldquo; Ctrl + S & rdquo; save it, just in case. Tip: There are two ways to enable the sleep function. One is to click sleep directly in the shutdown button of the start menu, and the other is to set the time in the computer power management, as long as the computer has no one to operate and achieve this setting. After that time, it will automatically go to sleep. In addition, the methods for enabling hibernation, mixed sleep, and leave mode are similar to the method for enabling sleep.
Second, long time not used "sleep", let the computer sleep well, except for a short time to leave the computer, sometimes we may leave longer, such as going out to work, maybe even one day is not at the computer, Then, at this time, it will not be turned off. If it is turned off, the programs, documents, web pages, materials, etc. opened in the computer will be reopened at the next boot! Do not shut down, if the day is not back, the power is off, all data It’s over, even if it’s sleepless! What should I do? It’s very simple! Enable another utility function ——“hibernate>! Compared to the sleep function, the data is saved in memory, and the sleep function is The data is saved to the hard disk. After entering the sleep state, all the accessories are not powered, so the power consumption is almost zero! And even if the power is turned off during the sleep state, the saved data will not be affected. When the computer wakes up, all the work remains. Can be restored normally. At the same time, because the data is saved on the hard disk, the speed of wake-up is much faster than restarting the computer. What is “sleep”? “Hibernate” is a power-saving state that is mainly designed for portable computers. In this state, the open documents and programs are saved to a file on the hard disk (can be understood as the memory status). Mirror), when the next boot, read data from this file, and load physical memory, this file is the same size as physical memory. Since the file written by memory during hibernation is a disk file, the speed of reading is much higher than that of accessing the disk during normal startup, so it is much faster than normal startup. In addition, it must be said that after the hibernation function is enabled, a hibernation file with the same size as your memory will be generated on the system disk to store the data in the memory. The user should pay attention to whether there is enough space in the system disk. For the stable operation of the system, the available space should account for about 10% of the system partition.
That is, the 50GB system partition should have at least 5 GB of free space. Tip: If you don't use your computer for a long time, it is best to choose to shut down. In addition, some networked programs, such as web applications that need to log in, instant messaging software (most instant messaging software can automatically reconnect after recovery, but can not save the original dialog window) and many network management programs may appear after recovery It is not working properly, so it is best to quit these programs before the system sleeps.
Three, leave time is not fixed with "mixed sleep", let the computer choose their own, above we talked about the short time to leave and leave for a long time, but sometimes life is always full of variables — — I I don't know how long I leave, what should I do? It may be an hour or a day. I am afraid that I will not be insured with sleep. I feel sleepy and sleepy. It is better to take it easy! The best way is to let the computer choose flexible —&mdash If it is uninterrupted, it will be restored from the memory; if it is powered off, it will be restored from the hard disk. And this is the “hybrid sleep” function! After the hybrid sleep is enabled, the computer will automatically go to sleep, but unlike the sleep state, the data stored in the memory will also be saved in the hard disk, so even if it is broken Electricity does not cause data loss, and when you wake up your computer, you can recover at a faster rate. This is the advantage of mixed sleep. What is "hybrid sleep" Mixed sleep is unique to Win7 and not available in WinXP, which combines all the advantages of sleep and hibernation. After entering the hybrid sleep, the system will first save the data in the memory to the hard disk, and cut off the power supply of other devices except the memory. In the recovery, if there is no power failure, the system will recover directly from the memory, it only takes a few seconds; if the power is off, because the memory is still stored in the hard disk, you can also recover from the hard disk without worrying about the data. Lost. Tip: Hybrid sleep mode requires the motherboard's power management to support S3 mode, but the general motherboard supports this mode. If your computer supports the Hybrid Sleep feature, then when you start Sleep after turning on the Hybrid Sleep feature, the system automatically goes into Hybrid Sleep.
4. Hanging up downloads & "Leave mode" Let the computer run low. In addition to the above-mentioned several situations, the computer will be in the state of “hanging up”, there is another very important application in daily life. —— hang up download. In the past, we usually started the download process, then turned off the monitor and speakers to let the computer run automatically. However, in this state, some non-working hardware will continue to consume power, such as video cards and sound cards. In Win7, we can enable the new "leave mode", which will not break the network, and will not affect the normal operation of the download program! What is the power consumption situation when entering the exit mode? After entering this mode, The hard disk and memory will remain in working state, and the CPU will enter a low power state (if the CPU does not support any energy saving technology, the leaving mode will let the CPU run at the lowest frequency & times; the lowest FSB to reduce its power consumption). Unwanted devices such as graphics cards and sound cards will be powered down. Although the power consumption is higher than the sleep mode, it is more power efficient than the normal boot download. What is the "leave mode"? The leave mode is similar to sleep, except that in the leave mode, file read and write operations can continue, while maintaining network connectivity, while unnecessary devices such as graphics cards and sound cards are turned off. The purpose of energy saving.
However, "Leave mode" requires hardware devices to support advanced power management and requires some setup. First of all, you need to set the option to turn off the hard disk and go to sleep in the power management to "Never", otherwise the hard disk is closed, how can you download it? Secondly, you need to modify the registry to open the registry with administrator privileges. Edit and navigate to "HKEY_LOCAL_MacHINESYSTEMCurrentControlSetControlSession ManagerPower", create a new “Dword(32-bit)” value in the right pane and assign it to “1” ), it will take effect after restarting. Then click the “sleep” button in the Win7 Start menu to automatically enter the “Leave Mode”. Tip: Do not press the computer power switch during the process of saving sleep or hibernation, otherwise it may cause problems that cannot enter the system. In addition, if you are using a laptop, if the battery is about to run out during battery-powered sleep, the system will automatically save the memory data to the hard drive and then turn off the power and go to sleep. At the same time, if it reaches the sleep time in the power plan, it will also enter the sleep state. Therefore, in general, the laptop only needs to enable the sleep function. If you want to save power, you can set the time to go to sleep in the power management options, so that you can be sure of nothing.
